Error given on install

Hello!
i have been doing the installation using the steps at https://about.gitlab.com/downloads/#raspberrypi2 on my Orange Pi but when I got to

curl -LJO https://packages.gitlab.com/gitlab/raspberry-pi2/packages/debian/(wheezy|jessie)/gitlab-ce-XXX.deb/download

it says in the terminal that

syntax error near unexpected token (’`

What should I do? Is this an error because it is an Orange Pi (which should be like a raspberry pi 2 considering it is running Raspbian), is it an error on my side, or on the server side?

Thank you.
